PROCESS OF G E'NERATING ACETYLENE GAS.

SPECIFICATION forming-part0! Letters Patent 596,139. dated December 28, 1897. Application flled October 16,1895. Serla1No.566,895. (No specimens.)

To all whom it may concern.-

Be it known that I, WERNERBOLTON, a subject of the Emperor of Russia, residing at Leipsic, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in the Generation of Acetylene Gas; and -I do hereby declare the follow- 3 ing to be a full, clear, and exact description of the invention, such as will enable others unskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in the generation of acetylene gas.

Acetylene gas I 5 suitable for-use in portable lamps, the rate at which it is generated by the action of the water upon the carbid of calcium-being so much in excess of the rate at which it is consumed as to establish a degree of pressure that would be dangerous in an ordinary lamp-reservoir.

' Hence the pregnation and can therefore be provided for accordin ly. The impregnation has the'fur-- ther eifec s of decreasing the weight oi the carbid and of preventing its decomposition by air which might otherwise enter it. lVhatI claim is .1. The process of at a regulated rate, which consists in first 1mpregn ating carbid of calcium-with a substance generation oftthe gas at a regulated rate becomes a condition precedent to the use,

impregnated'carbid pro-,

has not been hitherto made generating acetylene as.

substantially insoluble in water, and then subjecting the prepared car-bid to the action of water, substantially as set forth. 2'. Astep inthe process of generating acety lene gas at a regulated rate, which consists in impregnating stance substantially insoluble in water at a pressure below that of the atmosphere, sub.- stantial'ly as set forth. I

'3; Oarbid of calcium impregnated with a such as stearin, as a new composition of matter, substantially as set forth.

4. The process of slowly and continuously as required for con- .sumption in a lamp, which consists in first impregnating and filling. the interstices of fljecting the prepared mass to'the action of Water,"-substantially as set forth.

' .5.- As a new article of manufacture for the pregnating'mctalliecarbid with an inert substance, and then subjecting the prepared can bid totheaction oi water, whereby the pro-.
